Study On The Vowel Of The Baoan Language Based On The Acoustic Parameter Database

The dissertation is based on the idea of "a unified platform for speech and acoustic parameters of Chinese minority languages",and after we did Field investigation in "Three security guards" include Jislhishan Baoan,Dongxiang and Salar Autonomous County of the Dahejia town which are in Gansu Hui Autonomous Prefecture,on the premise of the establishment of "speech sound parameter database of security language",and on the basis of the traditional linguistic study of security language,using the research methods of modern linguistics,experimental phonetics theory and quantitative and qualitative carried on a systematic study of vowel system security.The dissertation consists of the introduction,the first chapter,the second chapter,the third chapter,the fourth chapter,the fifth chapter,the summary,the reference,the appendix,the acknowledgment and so on.The first chapter,the author mainly introduces the Baoan nationality and their language,as well as the research summary,the content,the purpose and the significance of the study,and the overall framework and function of the "security speech acoustic parameter database" of this language.The second chapter mainly analyzes the acoustic characteristics of the short vowel of Baoan Language.Through acoustic experiment we know that the word's first syllable,non first syllable has/e//e/i/(?)//o//u/six yuan short phoneme.The third chapter mainly analyzes the acoustic features of the Baoan language's long vowel.Through acoustic experiment we know that the first syllable of long vowels have/(?)://e://i://o://u:/five long vowels,non first syllable short vowels are only one long vowel phonemes,which is/(?):/.The fourth chapter mainly analyzes the acoustic characteristics of the short vowels and long vowels.By contrast,the phonics pattern of Baoan Language in line with Mongolia language group "inverted triangle" pattern characteristics.In Baoan language,the short vowel pattern is smaller and more narrow than the long vowel pattern overall(roughly).The fifth chapter mainly analyzes the acoustic features of Baoan Language complex vowels.After acoustic experiment we know that there are/u(?)//iu//(?)u/oi//ui//i(?)//(?)i//io//uo/nine complex vowels in Baoan Language.In the sixth chapter,the author mainly analyzes the stress of security words.From the experiment it is known that the word stress falls on the last syllable,and relating with the pitch duration and intensity and syllable types.In the seventh chapter,the author mainly analyzes the harmony law of the vowel in the security language.After statistical analysis and matrix analysis,the law of harmony of Baoan Language is in the type of destruction basically and there are residuals in somewhere.
